I AUTOMOBILE BRUSH SPRAY Filed Maj 16, 1934 P55 .5 INVENTOR LESTERGfimrznum:

BY g? ATTORNEY Patented Mar. 31, 1936 T OFFIE 4 Claims.

This invention relates to new and useful improvements in an automobilebrush spray.

The invention has for an object the construction of a. device asmentioned which is characterized by an arrangement whereby a hollowbrush base of metal is associated with bristles in a novel fashion forthe construction of a brush. A feature of the arrangement is the lack ofwooden parts.

Still further the invention particularly proposes an arrangement whereinthe hollow brush base is provided with a plurality of openings for thepassage of liquid among the bristles for better aid in cleaning with thebrush.

Still further the invention also proposes an arrangement wherein thehollow brush base is associated with a hollow handle and a pipe line fora supply of cleaning fluid.

Another one of the objects of this invention is the arrangement of aplurality of groups of bristles mounted upon said brush base andincluding threaded studs threadedly engaging into the brush base wherebythey may be removed and replaced when desired.

Still further the invention also proposes the provision of a valveadapted to control the supply of liquid within the hollow brush base andso control the supply of liquid to the bristles.

Another one of the objects of this invention is to so arrange the brushbase that it is convenient for cleaning various parts of a vehicle forexample, the spokes of the wheels, or of a different shape for cleaningthe windows.

Still further the invention also proposes an arrangement wherein thehollow brush base is arranged with openings for supplying water to thebristles, with these openings arranged in speciflc relation so as to bedirected away from the user so that the possibility of spraying the userwith water is eliminated.

Still further the invention proposes an arrangement whereby fourresilient strips are associated with certain of the groups of thebristles and are adapted to engage over and cover certain of theopenings for the purpose of selectively controlling the direction ofdischarge of the liquid.

Still further the invention proposes the construction of a device asmentioned which is simple and durable and which 'may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this invention:

The automobile brush spray according to this invention includes a hollowbrush base l0 connected with a hollow handle El and with a pipe line l2for the supply of water. The free end of the pipe line is provided witha coupling I3 by which it may be attached to a faucet'of a water supply.The other end of the hose I2 is connected with-a standard fitting M uponthe outer end of the handle I l by which it may be connected anddisconnected from the handle, said fitting being a conventionalcoupling. The interior of the handle I I is hollow, see Fig. 8, and thebrush base I0 extends into the front end of said hollow. The brush base[0 is of hollow construction closed at the outer end I5. A plurality ofgroups of bristles it are mounted upon the brush base and includethreaded stud portions l1 'threadedly engaging into the brush base. Saidhollow brush base i a is formed with a plurality of small openings I8arranged among the bristles for the purpose of supplying water to thegroups of bristles.

A valve controls the supply of water to the interior of the brush base.This valve comprises a conventional rotary valve 20 of tapered shape andis located in a peculiar position so as to simultaneously function alsoto hold the brush base connected with the handle. More particularly thevalve 20 engages transversely through the end of the handle and throughthe end of the brush base 20. This tapered valve is formed with apassage 2| which when located at right angles to the passage of thebrush base closes the passage but when in line allows the passage ofwater. The upper end of the valve 20 is provided with a handle 22 bywhich it may beturned. The lower end is equipped with a Washer 23 heldin position with a screw 24 which prevents the valve 20 from moving fromits position.

Each group of bristles comprises a small cup 25 having a plurality ofcuts 26 extended in from the edge so as to give it resiliency. Thebristles l6 are engaged at one of their ends into the cup 25 and tightlyclamped in position and so maintain their place. The bottom end of eachof the cups 25 is formed with a threaded stud I! for engaging into areceiving opening into the brush base.

A plurality of resilient straps 21 are associated with certain of thegroups of bristles and are clamped in position upon the brush base bythe threaded studs of the groups and are provided with valve members 28adapted to engage in certain of the openings [8 for the purpose ofclosing these openings. The arrangement is such that the hollow brushbase may be held in any inoperative position and openings l8 which aredirected to spray'water towards a user may thus be closed to eliminatethis inconvenience. More particularly each of the resilient strips 21 isformed intermediately with a bent portion, see Fig. 6, so as to normallytend to move the outer free ends downwards and so tightly close thevalve members 28 upon the openings. The clamped ends of each of thestrips 21 are formed with slots 29 extended in from the free end whicharrangement allows removal of the strips by slightly turning the cup 25to release the clamping action between the cups and the ends of thestrip. This arrangement permits complete removal of any of the resilientstrips and replacement in any other position.

- Furthermore the arrangement allows the resilient strips 2'! to beturned and clamped into a new position, as for example indicated by thedot an dash lines 21' in Fig. 3 for the purposes of being in idlepositions. In these idle positions none of the openings I8 arerestricted. With this arrangement, all, or any number of the openings l8may be closed when desired.

In Figs. 10 and 11 another embodiment of the invention has beendisclosed wherein an automobile brush spray is shown adaptedparticularly for the cleaning of the windows of a car. This brush sprayincludes a cup shaped member 30 formed with a closed end 3t providedwith a plurality of openings 32 for the passage of the water and with aplurality of groups of bristles l6 as previously described. Certain ofthe openings 32 may be closed by the provision of the resilient strips21 arranged to be clamped down by the studs of the cup shaped members ofthe bristles. These strips 2'! are provided with valve members 20 aspreviously described. The cup shaped member 30 is connected with ahollow handle 33 by which it may be readily manipulated. The end of thehandle is provided with a coupling 34 connected with a flexible hose 35to a supply of water.

While I have shown and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming Within the scope. of the invention asdefined in the appended claims.
